Homeopathic shot may shield cancer patients from chemo nerve pain
NCT ID NCT04715542
First seen Jun 25, 2026 · Last updated Sep 16, 2026 · Updated 3 times
Summary
This phase 3 trial tests whether a homeopathic remedy called Stibium metallicum praeparatum 6x can prevent or reduce nerve damage caused by the chemotherapy drug paclitaxel. The study will include 120 breast cancer patients who will receive either the remedy or a placebo injection three times a week during and for six weeks after chemotherapy. The goal is to see if this approach can reduce pain, tingling, and numbness, allowing patients to complete their cancer treatment without dose reductions.

- If it works, this could offer a way to prevent painful nerve damage from chemotherapy, helping patients complete their cancer treatment without dose reductions.
- What could go wrong
- This is a small, early-stage trial testing a homeopathic remedy, which has no proven biological mechanism. The effect may be no better than placebo, and results may not apply to all patients.
